Product details
Overview
88W8864-B0-NMMC/AZ from NXP is a dual-band 2.4/5 GHz IEEE 802.11ac (draft) 4×4 MIMO Wi-Fi SoC with integrated Arm Cortex-A9 CPU, supporting up to 1.3 Gbit/s PHY rate, 80 MHz channel bandwidth, and 256-QAM modulation. It delivers enterprise-grade throughput, beamforming-enhanced range, and hardware-accelerated AES-CCMP/WAPI security for access point and video bridge applications.
For engineers reviewing the 88W8864-B0-NMMC/AZ datasheet, 88W8864-B0-NMMC/AZ pinout, 88W8864-B0-NMMC/AZ application, or 88W8864-B0-NMMC/AZ equivalent, key selection considerations include PCIe v2.0 host interface compatibility, 4×4 beamforming implementation, LDPC coding support, 802.11h DFS compliance in 5 GHz, and integrated SRAM-based WLAN processing offload.
Technical Context
The 88W8864-B0-NMMC/AZ implements a full 4×4 MIMO PHY/MAC stack with explicit and implicit beamforming, operating across simultaneous 2.4 GHz and 5 GHz bands using 80 MHz channels and 256-QAM. Its integrated Arm Cortex-A9 core runs WLAN firmware and handles real-time MAC scheduling, spectrum management, and security protocol acceleration.
PCIe v2.0 (backward-compatible with v1.1) serves as the primary host interface, enabling low-latency, high-throughput data transfer to companion processors such as i.MX 6SoloX. The SoC supports 802.11e QoS for prioritized voice/video traffic and 802.11h DFS radar detection for regulatory-compliant 5 GHz operation.

FAQ
What is the primary host interface supported by the 88W8864-B0-NMMC/AZ?
The 88W8864-B0-NMMC/AZ uses PCI Express v2.0 (x1 lane) as its primary host interface, with full backward compatibility to PCIe v1.1. This interface enables deterministic, low-latency communication with companion processors like the i.MX 6SoloX. The 88W8864-B0-NMMC/AZ does not support USB, SDIO, or SPI host interfaces - PCIe is mandatory for functional operation.
Does the 88W8864-B0-NMMC/AZ support 802.11h Dynamic Frequency Selection (DFS)?
Yes, the 88W8864-B0-NMMC/AZ fully implements 802.11h DFS for radar detection in the 5 GHz UNII-2 and UNII-2e bands. It performs real-time pulse analysis and automatic channel switching within regulatory time limits. This capability is hardware-accelerated and requires no host CPU intervention, ensuring compliance in enterprise and service provider deployments where DFS is mandated.
Is beamforming implemented in hardware or software on the 88W8864-B0-NMMC/AZ?
Beamforming on the 88W8864-B0-NMMC/AZ is implemented in dedicated hardware blocks within the RF/baseband subsystem, supporting both explicit and implicit methods. Calibration, phase adjustment, and steering matrix computation occur autonomously without host CPU involvement. The 88W8864-B0-NMMC/AZ does not rely on software-defined beamforming algorithms executed on the Cortex-A9 core.
What security protocols are accelerated in hardware by the 88W8864-B0-NMMC/AZ?
The 88W8864-B0-NMMC/AZ includes hardware accelerators for AES-CCMP, WEP/TKIP, AES-CMAC, and WAPI cryptographic operations. These engines process encryption/decryption and message authentication inline with MAC frame handling, achieving wire-speed security without degrading throughput. The 88W8864-B0-NMMC/AZ does not require external crypto co-processors for any of these standards.
Can the 88W8864-B0-NMMC/AZ operate as a standalone Wi-Fi solution without an external host processor?
No - the 88W8864-B0-NMMC/AZ is designed as a PCIe-connected Wi-Fi SoC, not a self-contained module. While it contains an Arm Cortex-A9 core and internal SRAM, it lacks external memory interfaces, flash boot capability, and peripheral controllers required for autonomous boot and full system operation. The 88W8864-B0-NMMC/AZ must be paired with a host processor (e.g., i.MX 6SoloX) to function in production systems.
